Definitions

  • the invention relates to a process for the extrusion coating of a wood-based material strip with a thermoplastic in a continuous process, in which a hot melt adhesive layer is first applied in a molten form to the strip by means of a first extrusion tool and then the thermoplastic material is applied to the hot melt adhesive layer by means of a second extrusion tool.
  • the invention further relates to a device for performing such a method.
  • the prior art (DE-AS 1 264 303) recommends the use of a single extrusion tool for the application of the hot-melt adhesive layer and of the thermoplastic for a method of the type mentioned above.
  • Such a procedure also leads to the desired success of a smooth plastic coating in the case of strips which have been carefully produced from high-quality chipboard or hardboard and therefore have relatively smooth surfaces;
  • this result cannot be achieved with the known method if strips made of solid or plywood or strips made of inferior chipboard or hardboard have to be coated - in the first case the known method leads to bubbles between the coating and the strip core, in the second Fall to a visibility of the unevenness of the inferior chip or hard fiber material.
  • the invention was based on the object of improving the known method described in such a way that it can be used to provide all types of wood-based material strips, that is to say also those made of solid or plywood or of chipboard or hard fiber material of poorer surface quality, with a smooth coating of thermoplastic material .
  • This object can be achieved according to the invention in that, in a method of the type mentioned at the outset, the hot melt adhesive is cooled immediately after application and then its surface is smoothed using a calibration tool, in that the strip is then cooled together with the hot melt adhesive before the strip is introduced into the second extrusion tool and that behind the latter the coating of the bar is cooled.
  • the hot-melt adhesive coating is calibrated and smoothed after it has left the first extrusion tool and has already cooled somewhat, whereupon the strip, including the hot-melt adhesive coating, is cooled down to such an extent that the application of the molten thermoplastic in the second extrusion tool is no longer sufficient a bubble formation after leaving the second extrusion die, especially if the be layered bar is cooled as soon as possible after leaving the second extrusion tool.
  • the preferably heated calibration tool not only any bubbles that may have appeared are "ironed out smoothly", but during calibration, unevenness in the hot-melt adhesive coating caused by a reduced surface quality of the strip material is also eliminated, so that a smooth and even layer of thermoplastic material can then always be applied.
  • the steam developed by the wooden strip is derived in this known method, which is done with the aid of an extrusion tool in which a plastic tube is formed at a distance from the surface of the wooden strip; Furthermore, steam extraction ducts are provided in the extrusion die, which open into the space which tapers continuously on the surface of the strip until the extruded plastic hose comes into contact with it.
  • the known method according to FR-PS 1 243 405 was therefore unable to suggest the method according to the invention for several reasons: firstly, in the method according to the invention, in order to avoid the disadvantage described above, drying of the wood material strip should be avoided. Secondly, for reasons of time-saving production, a melted and therefore solvent-free adhesive (so-called hotmelt) should be used, while the known process according to FR-PS 1 243 405 works with a solvent-based filler, which results from the fact that in the known method the filler must be dried and cured by heating. The known method also does not disclose the step of smoothing and calibrating the filler.
  • the hot melt adhesive is warmed up again, if necessary also cooled further, in such a way that the surface of the hot melt adhesive has a temperature of preferably approximately 150 ° C.
  • the hot melt adhesive is then cooled as quickly as possible, in particular by means of an air stream, and at Longer heating intervals should be avoided by applying the thermoplastic.
  • the coating which now consists of hot melt adhesive and thermoplastic, should be intensively cooled as quickly as possible, for example by means of a water-cooled tool for smoothing and calibrating or by means of a water bath in order to prevent renewed blistering.
  • the hot melt adhesive is cooled after smoothing with the aid of the calibration tool to a surface temperature as low as possible, preferably in a cooling duct charged with a cooling air stream, so that the surface temperature of the hot melt adhesive is preferably at most about 60 ° C., preferably is less than 60 ° C and in particular at most approx. 30 ° C and as a result, when the thermoplastic is extruded, the hot melt adhesive / wood material interface area is no longer heated to such an extent that bubbles can form at this point.
  • a particularly advantageous embodiment of the method according to the invention provides for the measure to briefly heat and smooth again the surface of the hot-melt adhesive immediately before extruding the thermoplastic material.
  • hot melts are suitable for the process according to the invention, which form good adhesion promoters between a wood-based material and a thermoplastic, as is used for such coatings.
  • the hot-melt adhesive has a relatively high proportion of filler, since it can then be used to smooth out unevenness in the strip surface particularly well.
  • EVA resin ethylene vinyl acetate resin
  • coumarone resin coumarone resin
  • a filler as hot melt adhesive, chalk, heavy spar and the like are particularly suitable as fillers, and a preferred mixture has the following composition: Approx. 40% EVA resin, approx. 25% coumarone resin and approx. 35% chalk.
  • thermoplastic Any extrudable material which does not have to be processed at such high temperatures that the formation of bubbles cannot be avoided is suitable as a thermoplastic.
  • PVC is recommended as a cheap coating plastic.
  • a device which, like the alternative device according to DE-AS 1 264 303, has two injection molds which are arranged at a distance from one another in the direction of flow for applying the hot melt adhesive or the thermoplastic, wherein according to the invention there is one between the two injection molds
  • Calibration tool for the hot melt adhesive is arranged in order to calibrate the dimensions of the wood-based material strip coated with the hot-melt adhesive, "ironing" bubbles of the hot-melt adhesive layer and to ensure that imperfections in the surface of the wood-based material strip are properly filled.
  • the ratio of the advantageous distances between the first injection mold and the calibration tool on the one hand and between the latter and the second injection mold on the other hand depends on the application temperature and layer thickness of the hot-melt adhesive, the type of material of the wood-based material strip and the throughput speed of the strip and it can in particular be between vary about 1: 4 and about 1: 7; a ratio of approximately 1: 5 is particularly preferred; it has been shown that the hot melt adhesive between the first injection mold and calibration tool Sufficiently gassed so that after leaving the calibration tool, the hot melt adhesive layer is free of gas bubbles, while more intensive cooling is required before the second injection mold, because there it is not only a question of going through a heated injection mold, but also of the strip coated with hot melt adhesive the hot, molten thermoplastic is applied, which has to be cooled as quickly as possible after leaving the second injection mold, so that the heat content of the thermoplastic does not cause the hot melt adhesive to be warmed up again enough to cause bubbles and deformations.
  • the second injection mold with a so-called beak plate in front of the mouth of a channel for the thermoplastic, which widens slightly against the direction in which the strip runs.
  • the purpose of this beak plate is to heat the surface of the hot melt adhesive, if necessary to smooth it further, to feed the bar centrally to the adjoining nozzle plate and thus to bring about better adhesion of the thermoplastic to the hot melt adhesive.
  • the direction of travel of a wood material strip 10 through the device was marked with the arrow A.
  • the strip thus first passes through a first heated extrusion tool 12, which consists of two plates 12a and 12b, which together form an adhesive channel 12c, into which a molten hot melt adhesive (Holtmelt) is conveyed under pressure by known means, not shown.
  • the first plate 12a has an opening 12d which surrounds the bar 10 relatively closely, while an opening 12e forms a gap together with the surface of the bar 10, which would be the same width everywhere in a bar 10 with an ideal, smooth surface, so that would form an equally thick hot melt adhesive layer 14.
  • an uneven ledge surface and blistering can lead to an uneven surface of the hot melt adhesive layer 14.
  • a plate-like calibration tool 16 (spatula plate) with a calibration opening 16e, which is dimensioned somewhat smaller than the opening 12e and thus ensures that bubbles and other unevenness in the hot melt adhesive layer 14 can be leveled and compensated for.
  • the calibration tool 16 is preferably heated and is kept at a temperature of approximately 150 ° C. when using an EVA-based hot melt adhesive.
  • the strip 10 coated with the hot-melt adhesive layer 14 passes according to the invention through a cooling channel 20 which has an opening approximately matched to the cross-section of the strip 10 at the front and rear and into which a cooling medium, for example cooled air, is conveyed, so that at least the hot-melt adhesive layer 14 and preferably also the surface area of the wood material strip 10 can be intensively cooled.
  • a cooling medium for example cooled air
  • the strip 10 passes through a second extrusion tool 22, which in particular consists of four plates 22a, 22b, 22c and 22d, which are an inlet plate 22a, a deflection plate 22b for molten thermoplastic plastic to be extruded, a so-called beak plate 22c and a nozzle plate 22d.
  • a second extrusion tool 22 which in particular consists of four plates 22a, 22b, 22c and 22d, which are an inlet plate 22a, a deflection plate 22b for molten thermoplastic plastic to be extruded, a so-called beak plate 22c and a nozzle plate 22d.
  • the first two plates have openings 22e and 22f which surround the bar 10 at a considerable distance
  • the beak plate has an opening 22g which, according to the invention, widens in a funnel shape against the direction of flow A and, in its narrow area, thus corresponds to the cross section of the layer with the hotmelt adhesive layer 14 provided strip 10 is adapted that, since at least the plates 22c and 22d are heated, the surface of the hot melt adhesive layer 14 is heated to improve the adhesion of the plastic to be extruded and is smoothed again.
  • the distance between the calibration tool 16 and the beak plate 22c is approximately 100 cm, i.e. approximately five times the distance of the calibration tool 16 from the first extrusion tool 12.
  • the plastic layer 26 and the hot melt adhesive layer 14 are cooled intensively, e.g. by a flow of cooling air or by water cooling.
  • a water-cooled smoothing and calibration tool is recommended, in which the coated strip is cooled over a length of in particular 40 to 50 cm.
  • the passage opening of this tool is precisely adapted to the cross section of the coated bar.
  • the length of this calibration tool essentially depends on the throughput speed of the bar, the thickness of the coating, the melt temperature of the thermoplastic layer and the temperature of the cooling medium (usually water).
  • the extrusion tool 22 is kept at a temperature of approximately 180 ° C., especially when PVC is to be used for the plastic layer 26. Between the calibration tool 16 and the beak plate 22c, the hot melt adhesive layer 14 and the strip 10 are to be cooled to such an extent that the hot melt adhesive has a temperature of at most approximately 30 ° C. on the surface of the hot melt adhesive layer 14.
  • polyethylene and polypropylene are also particularly suitable for the coating, although in principle all thermoplastic materials can be processed using the method according to the invention.
  • Polyamide hot melt adhesives instead of EVA hot melt adhesives also lead to good results, although in principle all hot melt adhesives suitable for wood-based materials can be used.
  • the hot melt adhesive should not be processed at unnecessarily high temperatures.
  • the highest adhesive temperature should be around 190 ° C, when using a polyamide-based hot melt adhesive at around 230 ° C.
